STM32G474E-EVAL strange behavior in Source mode (USB PD)
I am working with demo board STM32G474E-EVAL and try to run example project in which board works in Source mode.
When I connect the power bank (HyperJuice Power Bank 130W USB-C) to the USB-C, the board starts constantly sending messages about its capabilities. In this case, the power bank does not answer anything and charging does not start.
The power bank works properly with other chargers and it can work in Source and Sink modes using various power profiles.
Can you explain what is happening and how I can start the Source mode so that the board starts charging the power bank.
